Legal Authority

10 VSA Sections 1263 and1265 provide that any permit for the discharge of waste into the waters of the state shall require operation and maintenance of the wastewater treatment facility as approved by the Secretary of the Agency, by qualified personnel in accordance with standards established by the Secretary. The Wastewater Treatment Facility Operator Certification Rule (67 KB, 12 pages Adobe Acrobat PDF) establish minimum standards of experience and knowledge required of chief and assistant chief operators of wastewater treatment facilities and are applicable to any Agency regulated activity which results in a requirement for a certified wastewater treatment facility operator.

General Policy

A facility having a discharge permit issued pursuant to 10 V.S.A.§1263 or §1265 requiring facility operation by certified operators shall employ both a chief operator and assistant chief operator. Certifications of chief operators shall be in the same numerical grade and class as the wastewater treatment facility classification. Assistant chief operators may be not more than two levels below that of the facility classification.


  • Applicants must be able to read and write the English language.
  • New applicants must be employed as an operator at a Vermont wastewater treatment facility at the time of application.
  • Education may be substituted for experience. This requires submittal of copies of a college transcript and degree with the application. Course work must be related to the field of wastewater.
  • Passing of the wastewater operator certification exam is also required for provisional certificate holders. Current certificates holders must also pass an examination to upgrade their certificate.
Facility Classification

For a determination of classification specific to your treatment process and design flow, please contact Carole Fowler at 802-490-6106 .

Domestic (DM) wastewater treatment facilities have five (5) classification levels. Class 1 facilities have simplified treatment processes (ie. pH adjustment only) with low design flows. Class 5 facilities are more complex (ie. mechanical sludge dewatering; rotating biological contactors, chemical precipitation, etc.) treatment processes with design flows of >5.0 MGD.

Industrial treatment facilities are classified in four categories; dairy, metal, paper and industrial.   There are also three (3) levels to each classification (I, II, and IV).  Again, each level of classification is based on treatment process and design flow.

Types of Certification

Provisional - An operator certified at any provisional grade and class has two years to meet the minimum qualifications and must be currently employed at a Vermont wastewater treatment facility. Provisional certificates are not renewable. Class III, IV and V provisional certificate holders must also meet a minimum one, two and three years respectively of wastewater experience at the time of application.
Full - An operator who is fully certified is issued a five year, renewable certificate. The individual has met the minimum years of experience, is currently employed as an operator at a Vermont wastewater treatment facility and has passed the required certification exam.
